Purchased this waffle maker right before Christmas. It worked fine. When we went to use it the second time the upper lid would not stay up. Accused our daughter of not putting it away properly. Purchased a second one. Used it one time. My husband happened to notice when he went to clean it that the knobs connecting the lid to the base melted/or broke off from the heat. Needless to say, my daughter is off the hook. There is a problem with the knobs that attach the lid to the base.
